    Robust topological superconductivity in spin-orbit coupled systems at higher-order van Hove filling

    Xinloong HanJun ZhanFu-Chun ZhangJiangping Hu...
    319-324页
    查看更多>>摘要：Van Hove singularities in proximity to the Fermi level promote electronic interactions and generate diverse competing instabilities.It is also known that a nontrivial Berry phase derived from spin-orbit coupling can introduce an intriguing decoration into the interactions and thus alter correlated phenom-ena.However,it is unclear how and what type of new physics can emerge in a system featured by the interplay between van Hove singularities(VHSs)and the Berry phase.Here,based on a general Rashba model on the square lattice,we comprehensively explore such an interplay and its significant influence on the competing electronic instabilities by performing a parquet renormalization group analysis.Despite the existence of a variety of comparable fluctuations in the particle-particle and particle-hole channels associated with higher-order VHSs,we find that the chiral p±ip pairings emerge as two stable fixed tra-jectories within the generic interaction parameter space,namely the system becomes a robust topolog-ical superconductor.The chiral pairings stem from the hopping interaction induced by the nontrivial Berry phase.The possible experimental realization and implications are discussed.Our work sheds new light on the correlated states in quantum materials with strong spin-orbit coupling(SOC)and offers fresh insights into the exploration of topological superconductivity.

    Topological spin textures in electronic non-Hermitian systems

    Xiao-Xiao ZhangNaoto Nagaosa
    325-333页
    查看更多>>摘要：Non-Hermitian systems have been discussed mostly in the context of open systems and nonequilibrium.Recent experimental progress is much from optical,cold-atomic,and classical platforms due to the vast tunability and clear identification of observables.However,their counterpart in solid-state electronic sys-tems in equilibrium remains unmasked although highly desired,where a variety of materials are avail-able,calculations are solidly founded,and accurate spectroscopic techniques can be applied.We demonstrate that,in the surface state of a topological insulator with spin-dependent relaxation due to magnetic impurities,highly nontrivial topological soliton spin textures appear in momentum space.Such spin-channel phenomena are delicately related to the type of non-Hermiticity and correctly reveal the most robust non-Hermitian features detectable spectroscopically.Moreover,the distinct topological soliton objects can be deformed to each other,mediated by topological transitions driven by tuning across a critical direction of doped magnetism.These results not only open a solid-state avenue to exotic spin patterns via spin-and angle-resolved photoemission spectroscopy,but also inspire non-Hermitian dissipation engineering of spins in solids.

    High-performance pulse light stable perovskite indoor photovoltaics

    Chen LiHaoxuan SunMin WangShan Gan...
    334-344页
    查看更多>>摘要：Perovskite solar cells offer great potential as a sustainable power source for distributed electronic devices that operate indoors.However,the impact of advanced lighting technology,especially the widely used pulse width modulation(PWM)technology,on perovskite photovoltaics has been ignored.Herein,for the first time in photovoltaics,we find that the light impact emitted by the PWM lighting system caused dynamic strain in perovskite thin films,induced phase separation,and accelerated the generation of metallic lead(Pb0)defects,leading to irreversible degradation of the cell performance after 27 h(T80).To address this issue,formamidinium triiodide(FAI3)is chosen to treat the surface of the perovskite and release residual stress,resulting in reduced lattice deformation during dynamic strain processes.Meanwhile,it suppresses harmful Pb0 defects and reduces Voc loss at low light intensity.The champion device achieves impressive power conversion efficiency(PCE)of 35.14％and retains 99.5％of the initial PCE after continuous strobe light soaking for 2160 h.

    Photo-induced versatile aliphatic C-H functionalization via electron donor-acceptor complex

    345-353页
    查看更多>>摘要：The ability to selectively introduce diverse functionality onto hydrocarbons is of substantial value in the synthesis of both small molecules and pharmaceuticals.In this endeavour,as a photocatalyst-and metal-free process,the electron donor-acceptor(EDA)strategy has not been well explored.Here we report an approach to aliphatic carbon-hydrogen bond diversification through an EDA complex constituted by HCl and SⅣ=O groups.As an efficient hydrogen atom transfer(HAT)reagent,chlorine radical can be produced via a proton-coupled electron transfer process in this system.Based on this unusual path,a photo-promoted versatile aliphatic C-H functionalization is developed without photo-and metal-catalysts,including thiolation,arylation,alkynylation,and allylation.This conversion has concise and ambient reaction conditions,good functional group tolerance,and substrate diversity,and provides an alternative solution for the high value-added utilization of bulk light alkanes.

    In vivo production of CAR-T cells using virus-mimetic fusogenic nanovesicles

    354-366页
    查看更多>>摘要：Engineered T cells expressing chimeric antigen receptor(CAR)exhibit high response rates in B-cell malig-nancy treatments and possess therapeutic potentials against various diseases.However,the complicated ex vivo production process of CAR-T cells limits their application.Herein,we use virus-mimetic fusogenic nanovesicles(FuNVs)to produce CAR-T cells in vivo via membrane fusion-mediated CAR protein delivery.Briefly,the FuNVs are modified using T-cell fusogen,adapted from measles virus or reovirus fusogens via displaying anti-CD3 single-chain variable fragment.The FuNVs can efficiently fuse with the T-cell mem-brane in vivo,thereby delivering the loaded anti-CD19(αCD19)CAR protein onto T-cells to produceαCD19 CAR-T cells.These αCD19 CAR-T cells alone or in combination with anti-OX40 antibodies can treat B-cell lymphoma without inducing cytokine release syndrome.Thus,our strategy provides a novel method for engineering T cells into CAR-T cells in vivo and can further be employed to deliver other ther-apeutic membrane proteins.

    Resonance between projected Tibetan Plateau surface darkening and Arctic climate change

    Shuchang TangShilong PiaoDavid M.HollandFei Kan...
    367-374页
    查看更多>>摘要：The Tibetan Plateau(TP)exerts a profound influence on global climate over million-year timescales due to its past uplift.However,whether the ongoing climate changes over the TP,particularly the persistent reduction in its local albedo(referred to as"TP surface darkening"),can exert global impacts remains elu-sive.In this study,a state-of-the-art coupled land-atmosphere global climate model has been employed to scrutinize the impact of TP darkening on polar climate changes.Results indicate that the projected TP darkening has the potential to generate a stationary Rossby wave train,thereby modulating the atmo-spheric circulation in the high-latitudes of the Northern Hemisphere and instigating a dipole-like surface air temperature anomaly pattern around the Arctic region.An additional experiment suggests that the projected Arctic warming may in return warm the TP,thus forming a bi-directional linkage between these two climate systems.Given their association with vast ice reservoirs,the elucidation of this mech-anism in our study is crucial in advancing our comprehension of Earth system climate projections.

    Abrupt climate fluctuations in Tibet as imprints of multiple meltwater events during the early to mid-Holocene

    Hongxi PangWangbin ZhangShuangye WuTheo M.Jenk...
    375-381页
    查看更多>>摘要：Understanding the impact of meltwater discharge during the final stage of the Laurentide Ice Sheet(LIS)has important implications for predicting sea level rise and climate change.Here we present a high-resolution ice-core isotopic record from the central Tibetan Plateau(TP),where the climate is sensitive to the meltwater forcing,and explore possible signals of the climate response to potential LIS meltwater discharges in the early to mid-Holocene.The record shows four abrupt large fluctuations during the 7-9 ka BP(kiloannum before present),reflecting large shifts of the mid-latitude westerlies and the Indian summer monsoon(ISM)over this period,and they corresponded to possible LIS freshwater events documented in other paleoclimate records.Our study suggests that multiple rapid meltwater discharge events might have occurred during the final stage of LIS.The finding implies the possibility of rapid sea level rise and unstable climate in the transition zone between the mid-latitude westerlies and the ISM due to fast polar ice retreat under the anthropogenic global warming.

    Large-n quasi-phase-pure two-dimensional halide perovskite:A toolbox from materials to devices

    Zijia LiYuexin LinHao GuNan Zhang...
    382-418页
    查看更多>>摘要：Despite their excellent environmental stability,low defect density,and high carrier mobility,large-n quasi-two-dimensional halide perovskites(quasi-2DHPs)feature a limited application scope because of the formation of self-assembled multiple quantum wells(QWs)due to the similar thermal stabilities of large-n phases.However,large-n quasi-phase-pure 2DHPs(quasi-PP-2DHPs)can solve this problem perfectly.This review discusses the structures,formation mechanisms,and photoelectronic and physical properties of quasi-PP-2DHPs,summarises the corresponding single crystals,thin films,and heterojunc-tion preparation methods,and presents the related advances.Moreover,we focus on applications of large-n quasi-PP-2DHPs in solar cells,photodetectors,lasers,light-emitting diodes,and field-effect tran-sistors,discuss the challenges and prospects of these emerging photoelectronic materials,and review the potential technological developments in this area.
